Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-13303/ (Markdown: https://insights.sbomify.com/MAL-2026-13303/index.md)","id":"MAL-2026-13303","markdown":"https://insights.sbomify.com/MAL-2026-13303/index.md","name":"MAL-2026-13303","record":{"aliases":["GHSA-v749-ghvj-538r"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Requiring dolyame-boxy-desktop-bnpl-footer causes _platform.js to execute at load time: it reconstructs destination hostnames from split string arrays (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev), downloads a platform-specific binary, writes it to /var/tmp/.cache_\u003chex\u003e on Unix or %TEMP%/dotnet_diag_\u003chex\u003e.exe on Windows (masquerading as a.NET diagnostic file), chmods it 0755, and spawns it detached via /bin/sh -c '\u003cpath\u003e \u0026' or cmd.exe /c start /b.
